BACKGROUND OF THE INVENTION
[0001] This invention relates to attachable eyeglasses which can be worn over normal eyeglasses.
[0002] Normal eyeglasses are worn for recovery of poor eye sight. Other special eyeglasses
are used, for example, for the protection against glare and also for the protection
of human eye itself. When a person wearing the normal eyeglasses wants to use other
types of eyeglasses for protection against glare, various problems occur.
[0003] One who wears normal eyeglasses obtains a pair for correcting his or her eys sight.
The eyeglasses also reflect that person's own tastes. In order to make eyglasses which
can be equipped both for eyesight correction and, for example, sunglasses, is very
expensive. Even if one can afford this type of eyeglass, the manufacturer may run
into difficulty in producing such a lens. In theory and technically, it is possible
to produce such a lens, but in reality, such a job is difficult.
[0004] When a person who wears eyeglasses wants to use special eyeglasses for, for example,
glare protection, first normal eyeglasses are taken off and then the sunglasses are
put on. The sunglasses cannot ensure normal eye sight unless they are prescription
sunglasses.
[0005] In view of these situations, "clip on glasses" are used. "clip on glasses" are equipped
with a front frame which holds glare preventive lenses and are hooked onto normal
eyeglasses with a clip, when required. Thus, the wearer has both normal eyeglasses
and other purpose glasses simultaneuosly. The prior art, however, has the following
defects : (1) extra weight of the "clip on glasses" is added to the normal eyeglasses,
and as a result, a total weight of almost two pairs of eyeglasses causes an oppressive
sensation to the wearer; (2) when the sizes and shapes between the normal eyeglasses
and the "clip on glasses" are different, this situation results in an ugly and odd
look; and (3) the contact between the normal eyeglasses and the "clip on glasses"
causes the scratches or damage to one or both of lenses.
SUMARRY OF THE INVENTION
[0006] A main object of the present invention is to provide attachable eyeglasses which
fit comfortably and correctly over normally worn eyeglasses without being odd looking
and ugly.
[0007] Another object of the present invention is to provide attachable eyeglasses wherein
an extra weight is dispersed properly in various directions so as not to invite a
sense of incongruity to the wearer when worn.
[0008] Yet another object of the present invention is to provide attachable eyeglasses wherein
scratches and damage caused by contact of each lens between the attachable eyeglasses
and the normal eyeglasses are properly prevented.
[0009] The above-mentioned objects are obtained by providing an attachable eyeglass front
frame which is considerably larger than that of normal eyglasses. The front frame
has a brow bracket on an upper end, overhanging the normal eyeglass front frame, extending
over the wearer's eye brow and finally contacting the wearer's forehead. The contacting
portion of the brow bracket is formed with a soft quality resin for providing a natural
bumper effect. A pair of ribs are formed between the brow bracket and the front frame
to hold and stabilize the normal eyeglasses. On a temple piece of the attachable eyeglasses,
a fastener is provided to hold the temple piece of the normal eyeglasses, or alternatively,
the temple piece is formed bigger than that of the normal eyeglasses. Further, when
needed, a pair of nose pads is provided below the nose pads of the normal eyeglasses.
These features reduce or eliminate the unpleasant feeling to the wearer when worn.
[0010] These objects, together with other objects and advantages which will be subsequently
apparent, reside in the details of construction and operation as more fully hereinafter
described and claimed, reference being had to the accompanying drawings, forming a
part hereof, wherein like reference numerals refer to like parts throughout.

DETAILED DESCRIPTIONS OF THE PREFERRED EMBODIMENTS
[0012] With reference to FIG.1 and FIG.2(a) and (b), the first embodiment will be explained
below.
[0013] A front frame(1) is produced having dimensions of, for example, 150 millimeters(mm)
wide and 65 mm high. The front frame has a curve which curves toward the wearer's
face. The front curve is a considerably dull line compared with normal eyeglasses
so that the curve line can adapt properly to the worn normal eyeglasses. Acrylic resin
lenses having a mirror coating are, for example, implanted within the frame. On the
upper part of the front frame(1), a brow bracket (11) is formed as one body extending
toward the wearer's head. When the attachable eyeglasses are worn over normal eyeglasses,
the brow bracket(11) contacts the wearer's forehead whereon the weight of the attachable
eyeglasses is partly supported.
[0014] The front flame(1) has side brackets(3) on both ends. The front frame(1) and side
brackets(3) are formed as one production. As shown in FIGS.2(a) and 2(b), on the inner
surfaces of the side brackets(3), fastener means(31) are formed facing each other
so that the means(31) can tightly hold or release the temples of the normal eyeglasses.
This fastener means(31) comprises a thin temple receiver(31a) and a cap(31b). When
the cap(31b) is snapped forcibly into the upper end of the fastner means(31),the temple(G₁)
of the normal spectacles(G) is correctly and sufficiently locked. In the first embodiment,
the fastener means(31) adopts the plastic hook style. But as shown in FIG.3(a) and
3(b), metal wire material is also available as well as a magic fastner style(velcro)
shown in FIG.4(a) and 4(b).
[0015] A second embodiment is now explained in accordance with FIG.5, FIG.6 and FIG.7.
[0016] The second embodiment is similar to the first embodiment in that the front frame(1)
is having the same size and same style, and has synthetic resin as the lens material.
On the upper end of the front frame(1), a brow bracket(11) is formed as one body with
the front frame(1). On the top end of the brow bracket(11), a bumper means(12) is
equipped with a silicon rubber pad. When this frame is worn over the normal eyeglasses(G),
the bumper means(12) contacts the wearer's forehead, whereon the weight of the attachable
eyeglasses is partly supported. Nose pads(2), composed by silicon rubber, and a metal
arm are located beneath the center of the front frame(1). These nose pads(2) and nose
surface also support partly the weight of the attachable eyeglasses.
[0017] Temple pieces(3) are connected with the front frame(1) by hinges(not shown) which
allow the temples to fold. When the attachable eyeglasses of the present invention
are used, the temple pieces(3) are racked on a wearer's ears crossing over the temples(G₁
.G₂) of the normal eyeglasses(G). On the back side(inner side) of the temple piece(3),
a recess(not shown) is formed therein so that the temple pieces(3) are stable and
will not move.
[0018] A third embodiment of the present invention is explained in accordance with FIG.8,
FIG.9, FIG.10 and FIG.11. The third embodiment is similar to the first embodiment
in that a front frame(1) is produced having the same size. The style of the third
embodiment looks semi-cylindrical when viewed from above as shown in FIG.7. On the
upper end of the front frame(1), a brow bracket(11) is formed as one body with the
front frame(1) and is equipped with a bumper means(12) comprising silicon rubber.
The brow bracket(11) contacts the wearer's forehead when worn over the normal eyeglasses(G),
and it partially supports the weight of the attachable eyeglasses. Beneath the brow
bracket(11), a rib(13 - FIG.9) is employed to receive the upper part of the normal
eyeglasses(G). The rib(13) ensures the immobility of the normal eyeglasses(G) and
the attachable eyeglasses. Nose pads(2) formed by silicon and a metal arm are located
beneath the center of the front frame(1). These nose pads(2) are located below those
of the normal eyeglasses(G) to partially support the attachable eyeglasses. Temple
pieces(3) having a total length at 155 millimeters are connected with the front frame(1)
by hinges(not shown) which allow the temple pieces(3) to fold. When the attachable
eyeglasses of the present invention are used, the temple pieces(3) hold the temples(G₁
.and G₂) of the normal eyeglasses(G) tightly against the wearer's head from the side
face to the back of the wearer's head. this allows both the normal eyeglasses and
the attachable eyeglasses to be stably connected.
[0019] FIG.12 is a diagram of a variation in the attachable eyeglasses according to the
third embodiment, wherein a side lens in the temple piece is also available.
[0020] In the three embodiments which have been explained, the shape of the front frame(1)
can have various other shapes such as, for example, a goggle shape as shown in FIG.13(a)
and 13(b). At the same time, as shown in FIG.14(a) and 14(b), the lenses can be equipped
along the front frame(1) including the temple sizes, either continuously or separately.
[0021] This invention describes the front frame and temple pieces as being made of synthetic
resin. These parts, however, can be obtained by metal binding works or pressing works
having free styles. With regard to implanted lenses, it is preferrable to use mirror
coated lenses therein, however, all kinds of beam attenuating lenses such as, for
example, colored lenses, polarized light lenses, and photochromic lenses, can be used.
[0022] As explained above, the attachable eyeglasses developed by this invention can eliminate
the various uncomfortable effects when using attachable eyeglasses. That is, a large
front frame conceals the normal eyeglasses, a brow bracket formed on the upper part
of the front frame contacts a wearer's forehead to partly support the weight of the
attachable eyeglasses, and an unpleasant feeling experiences by the wearer caused
by the double eye glass weight is avoided. As explained above with respect to the
second embodiment, extra nose pads are provided on the attachable eyeglasses so that
the burden on the wearer's nose is highly reduced. The front frame is large in size
which helps to hide the odd protruding of the normal eyeglasses which are already
being worn. Fastening means and rib formation prevent the lenses of the attachable
eyeglasses and those of the normal eyeglasses from contacting each other and causing
damage or cracks in the lenses.
[0023] The foregoing is considered as illustrative only of the principles of the invention.
Further, since numerous modifications and changes will readily occur to those skilled
in the art, it is not desired to limit the invention to the exact construction and
applications shown and described, and accordingly, all suitable modifications and
